Take-Home Naloxone Access and Use among Older Adults Living with Pain: A Scoping Review.

Background: Opioids are a common treatment for older adults living with pain. Given high rates of polypharmacy and chronic comorbidities, older adults are at risk of opioid overdose. Evidence is now available that take-home naloxone (THN) supports reduction of opioid-related harms. It is unknown what THN initiatives are available for older adults, especially those living with chronic pain.

Objective: To summarize the literature regarding THN, with a focus on older adults using opioids for pain, including facilitators of and barriers to THN access, knowledge gaps, and pharmacist-led initiatives.

Data sources: A scoping review, guided by an established framework and PRISMA-ScR guidelines, was performed. Methods involved searching 6 bibliographic databases (MEDLINE, Embase, Scopus, APA PsycINFO, Web of Science Core Collection, and PubMed), reference harvesting, and citation tracking. Searches were conducted up to March 2023, with no date limits applied; only English publications were included.

Study selection and data extraction: Study eligibility was determined according to preset criteria, including age; discrepancies were resolved by discussion and consensus. Data were extracted and categorized through thematic analysis.

Data synthesis: Four studies met the eligibility criteria. All 4 studies detailed THN programs in primary care settings involving older adults taking opioids for pain management. Two of the studies highlighted patient-specific risk factors for opioid overdose, including concomitant use of benzodiazepines and/or gabapentinoids, mean morphine milligram equivalents per day of at least 50, and previous opioid overdose. Two of the studies assessed patient knowledge of opioid overdose management and attitudes toward THN. Educational programs increased patients' interest in THN.

Conclusions: The literature about THN for older adults living with pain is limited, and no literature was found on pharmacist-led initiatives in this area. Future research on THN provision for older adults, including pharmacist-led initiatives, could help to optimize care for older adults living with pain.
